Young children engage with digital technologies from a very young age. Often this is considered detrimental to their social development as it is seen as a socially isolating experience. This paper presents the findings of an Australian Research Council funded research project that focused on what characterises infants and toddlers peer-to-peer…

Children raised in chaotic households show affect dysregulation during later childhood. To understand why, we took day-long home recordings using microphones and autonomic monitors from 74 12-month-old infant-caregiver dyads (40% male, 60% white, data collected between 2018 and 2021). Caregivers in low-Confusion Hubbub And Order Scale (chaos)…

This longitudinal study investigated parents' different pretend play behaviors (substitution, animation, and role enactment) to their infants during free play and the bidirectional links with infants' vocabulary development at 14 months (Time-1: N = 34, M[subscript age] = 14.23 months) and 20 months (Time-2: N = 34, M[subscript age] = 20.33…

Speech development occurs in highly variable environments; however, little is known about the effect of situational context on emerging infant vocalizations. At 4 time points (4, 6, 9, and 12 months), we longitudinally measured vocalizations of 104 White infant-caregiver dyads (41 girls) during three play contexts: book-sharing, toy play, and…

The First Year Inventory (FYI) is a parent report screening measure, aimed at identifying the risk of autism spectrum disorder (ASD) in 12-month-old infants. This study aimed to investigate the utility of FYI within the Chinese community and develop a short version, encompassing both a low-risk sample and a high-risk sample comprising infants with…

This study examined various formats and strategies used by caregivers in early reading activities, and assessed how they were tailored to the developmental stages of infants and toddlers. Participants included three caregivers from classrooms for ages 0-12, 13-18, and 19-24 months, and the director of an early childhood education center known for…

Background: Feeding is an important health consideration for children with Down syndrome due to their increased risks for feeding challenges and overweight/obesity. Healthcare providers play an important role in providing feeding guidance to families; however, there is limited research on feeding children with Down syndrome and the role of…

Parental language input is a key predictor of child language achievement. Parentese is a widely used style of child-directed speech (CDS) distinguished by a higher pitch and larger pitch range. A recent parent coaching randomized control trial (Parentese-RCT) demonstrated that English-speaking US parents who were coached to use parentese with…

Compared with the more physically fragile extremely/very preterm children (E/VPT), moderate-to-late preterm (MLPT) children--the large majority of preterm births--are underrepresented in research. This gap persists despite evidence that MLPT children exhibit more difficulties than full-term peers in certain domains. This scoping review surveys the…

Objective: To examine associations between cognitive stimulation in the home at 6 months and maternal feeding styles at 24 months, direct intervention effects of Smart Beginnings (SB) on feeding styles, and potential indirect effects of SB on feeding styles via earlier intervention effects on cognitive stimulation. Methods: Single-blind, two-site…

The Maryland's Premature Infant Developmental Enrichment (PRIDE) program is a unique collaborative endeavor between the University of Maryland School of Medicine and the Part C program for Baltimore City residents (Baltimore Infants and Toddlers Program; BITP). To evaluate the impact of PRIDE, the current study compared premature infants from…

This study assessed the extent to which visuospatial processing, as measured by visual scanning behaviour, was associated with infants' ability to recognize mirror image and structurally distinct three-dimensional objects. Simplified Shepard and Metzler (1971) images were employed. Using a remote eye-tracker, infants ages 10 to 17 months (n = 130)…

Early childhood intervention is particularly cost-beneficial when it reduces justice involvement, but ingredients that contribute to this outcome are unknown. The goal of this study was to estimate the effects of two common early childhood intervention ingredients--home visits and center-based education--on juvenile justice involvement. The Infant…

The development of copying behaviours of a group of infants from 9 to 15 months of age is analysed. These behaviours are classified according to their type (mimetic or imitated) and function (instrumental, social or hybrid). The function of the behaviours is derived from observable indicators linked to dyadic interaction. Mimetic behaviours are…

Infant motor development is affected by the sociocultural context in which it takes place. Because societal and cultural practices are dynamic, this exploratory study examined whether the ages at which infants typically learned to crawl, cruise, and walk changed over the past 3 decades. We compiled archival data from 1,306 infants born between…
